In-Store Exclusive

This one's worth the trip to the store.

Brands like Weber, Milwaukee, Yeti, and DeWalt restrict where their products can be sold online — and for good reason. In-store buyers get authentic products, full manufacturer warranty, and access to pricing that simply isn't allowed to be advertised on the web.

  • Authorized dealer network · Full manufacturer warranty & support
  • Guaranteed authentic · No counterfeits, no gray-market resellers
  • The brands set these standards · Be wary of sellers who don't follow them

Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

OSI Quad Max Tundra Gray Elastomeric Polymers Caulk Sealant, 9.5 oz is a high-performance, permanently flexible sealant designed for interior and exterior applications where movement and moisture are a concern.

  • Elastomeric polymer formula provides long-lasting flexibility that tolerates expansion and contraction without cracking.
  • Permanently flexible seal maintains a watertight barrier in wet environments, reducing the need for frequent re-sealing.
  • Moisture resistant and mildew resistant, making it ideal for bathrooms, kitchens, basements, laundry areas, and exterior installations.
  • Paintable finish lets you seamlessly match trim, siding, tile, drywall textures, or existing surfaces.
  • Cartridge packaging designed for standard caulk guns, enabling precise, clean application even in tight gaps.
  • Color: Tundra Gray (color family: Gray) to blend with gray surfaces and exterior finishes.
  • Suitable for indoor and outdoor use, including around windows, doors, plumbing, gutters, and siding joints.
  • Cleanup is simple with mineral spirits while the product cures to form a durable seal.
  • Not fire or high-heat resistant—use in appropriate environments only.
  • Coverage area: 29.1

Designed for homeowners, DIYers, and professionals tackling sealing projects where reliable adhesion and enduring flexibility matter. OSI Quad Max delivers a robust, weather-ready seal that holds up against moisture, temperature shifts, and daily wear, helping you achieve a cleaner, longer-lasting finish without compromise.

Practical tips for best results: prepare surfaces by cleaning and drying thoroughly, apply with a compatible caulk gun, tool the bead for a smooth profile, and follow label guidance for curing times. If applying in areas with heavy moisture or sun exposure, plan for re-evaluation over time to maintain a seamless seal.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a co-op banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
